PhysicsYou accidentally got the right answer. Correect solution is following: The Earth makes one revolution (2π) during 1 year => the angular displacement for 5 days is θ= 2π5/365 = 0.086 rad. The angular velocity of the Earth is ω= θ/t = 0.086/5...

PhysicsIf your question is: If a rod is moving at a velocity equal to 1/2 the speed of light parallel to its length, what will a stationary observer observe about its length? The answer is L=L₀sqrt{1-(v/c)²}=0.866L₀ The length of the rod will decrease.

physics to be conceptualizeIn an isolated system where only conservative forces cause energy changes, the kinetic energy and potential energy of the system can change, but the mechanical energy of the system cannot change. The work done by a conservative force on a particle moving between two points ...
